Mac OS X pasteboard watcher and copy/paste manager

Jello is a light and clean library for dealing with the Mac OS X
pasteboard through the pbcopy and pbpaste commands.
It also provides a binary that you can run in the background, that
will process all strings pasted to the clipboard however you like -
includes examples for shortening copied urls automatically as well
as fixing ‘broken’
GrabUp
URIs for you.
